What is the Volume of a Debris Flow? part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet to estimate the volume of volcanic deposits using map, thickness and high-water mark data from the 2005 Panabaj debris flow (Guatemala).

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.

How Do We Estimate Magma Viscosity? part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

Bubbles in Magmas part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

Porosity and Permeability of Magmas part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

What is the Volume of the 1992 Eruption of Cerro Negro Volcano, Nicaragua? part of Examples
SSAC Physical Volcanology module. Students build a spreadsheet to calculate the volume a tephra deposit using an exponential-thinning model.

What is the Relationship between Lava Flow Length and Effusion Rate at Mt Etna? part of Examples
SSAC Physical Volcanology module. Students use Excel to determine a log-log relationship for flow length vs effusion rate and compare it with a theoretical expression for the maximum flow length.

Frequency of Large Earthquakes -- Introducing Some Elementary Statistical Descriptors part of Examples
Spreadsheets Across the Curriculum module. Students examine the number of large earthquakes (magnitude 7 and above) per year for 1970-1999 and 1940-1999. QL: descriptors of a frequency distribution.

Tale of Two Cities (and two hurricanes): New Orleans part of Environmental Geology:Activities
This is an activity that uses the spreadsheet program Excel to explore the origins of subsidence in New Orleans. There are two versions. The first is a traditional Spreadsheets Across the Curriculum (SSAC) module ...

Mined-Over Matter: Remembering Copper Mining at Keweenaw National Historic Park, Upper Peninsula Michigan part of Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. Students calculate the amount of rock removed and the value of copper produced at the great Keweenaw District up to 1925.
